Need for geo analyses?

Examples from my research

Example: Site selection

Agrale: site selection

• Most recent orto-photo images
• Image classification and interpretation
• vegetation plots – predefined abandonment class
• 26 habitat classes
• habitats of interest (BLFO | CGR | HGR | PA | SHR | WL | OFO | HD) == proxy for woody structure at plot!
• 4 abandonment classes * 8 habitat classes * 5 replicates * 4 countries* - random selection from defined strata *height layers

Agrale after site selection

Agrale - birds

• Systematic sampling on Passerine bird communities
• Standard point-count method
• circular sampling plots 100m radius

Agrale - birds/landscape

Example: data collection, geocoding

• storks via Google maps API from R

• schools in Croatia via HERE Nokia API from R

White stork habitat suitability

• Combination of regression techniques and geostatistics
• Detect suitable yet still not occuoied areas (to be important in predicted climat changes)
• Predict extected nest densities at 1km scale

Example: data collection

Black sork, Slovenia

• Remote sensing (satelite tracking)
• Animal movement
• Habitat usage
• Lidar point cloud analysis
